Re: The bottom line on Ham radio
Keep working at it!
In theory, your radio is capable of receiving SSB and CW signals over a wide frequency range, including HF (3-30 mHz) where most of the marine SSB transmissions take place.
However, the radio does not have a true product detector; rather, it uses IF filtering for SSB and CW modes. This is from the Icom manual:
The transceiver uses a general purpose IF filter to
receive signals in LSB, USB, CW and AM modes.
So, when you receive signals in LSB or USB mode,
the opposite side band signal is not fully attenuated.
At the same time, since the same filter is used for CW
reception, you may have difficulties seperating the
CW signal from other signals in the crowded band.
What that means is that you may indeed be able to hear some marine SSB transmissions, but not as clearly as you would with a true SSB radio. And, they won't be anywhere near as easy to tune.
Still, it's worth a try. Listen in on 8152 kHz every morning beginning at 0830 Eastern time. You may hear one or more of the many boats checking into the Cruizheimer's Net on marine SSB. And, throughout the day you may hear some traffic on the ham frequency 14,300 kHz where the Intercon Net and the Maritime Mobile Service Net take place.
As noted above, you really need a General Class ham license for maritime operation. I'd work on that...spend your time boning up, get the license, then get a real SSB transceiver. You can get a ham or even marine SSB rig for $200 and up. Even the lower cost transceivers have excellent receivers which will afford you the opportunity to listen as much as you like and, eventually, to transmit as well.
Good luck and 73,.
